STEAM-ENGINE REVERSING-GEAR.

SPECIFICATION forming part of Letters Patent No. 714,368, dated November 25, 1902.

Application filed October 24,190

1 Serial No. 79,766. (No model.)

1'0 all whom, it may concern.-

Be it known that I, LANDY D. EPPERSON, a citizen of the United States, residing at Mansfield, in the county of Richland and State of.

a single eccentric can be shifted on a spindle in a curve so as to occupy either position of the two eccentrics on a link reverse; sec- 2') ondly, to secure a simple reversing mechanism with only three main parts; thirdly, to

make a durable reversing-gear which will wear only when being reversed, and,fourthly, to prevent any slip of the eccentric by the relative construction and arrangement of the parts.

Figure 1 of the drawings is a plan View of my invention with the parts in conjunction as used; Fig. 2, an enlarged view of the eccentric with its shell and spindle; and Figs. 3 and 4, end views, respectively, of the spindlebearing piece and the shaft-sleeve which is operated by the lever. Fig. 5 is a vertical side elevation; and Fig. 6 is an end view, the shaft being in cross-section.

In the drawings, A represents the eccentric-shell with its diagonal slot at and its spindle a. This shell is secured adjustably to the engine-shaft O by means of thepiece D, which has a bearing d for the spindle a and the collar (1, held to shaft by a set-screw 01 E is the sliding sleeve, moved back and forth by the reversing-lever,whose collar fits in the annular groove 6, said lever not being shown. By my swinging eccentric I can place it in exactly the same position as with the two eccentrics in a link-motion.

In reversing gears which shift straight across the shaft the work is not properly done at the valve, while there is more resistance to the action of the reversing-lever than is necessary. The sliding sleeve E carries a stud e, which may carry a friction-roller to work in the slot at o the eccentric as said sleeve is slid on the haft C in a straight line, while the eccentric turns with its spindle a in the bearing 01, so as to move across the engine-shaft. The sleeve E has a screw e which passes therethrough and works in a longitudinally-straight slot of the shaft to prevent said sleeve from turning.

What I claim as new is-- and a spindle at opposite or nearly opposite thereto, a fixed collar d with a bearing d, and a sliding sleeve E in combination with an engine-shaft, to form a reversing-gear as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

LANDY D. EPPERSON.
